A 26-year-old self-made millionaire shares his top 5 tips for career success

By the time he was 20, Brian Wong was a self-made millionaire. The mobile advertising company he founded, Kiip, works with major companies including McDonald's and Coca-Cola and is on track to do $20 million this year.

Wong is remarkably savvy about how he strategizes in business, and he wrote about his tips to success in his book, "The Cheat Code."

Wong calls asking for things, whether it be help, guidance or funding, "the magic wand for business and even in life." Because if you ask and get a "no," you're still exactly where you were before you asked the question.

"Honestly, I never feel defeated by a 'no,'" Wong tells CNBC. "My first reaction when someone says 'no': It's your loss. Like, you said no you're not going to do this, but someone else is going to do this. And they're going to make way more money than you."

In particular, Wong shares this advice with entrepreneurs looking to raise money and his sales team when they are pitching a product to a new customer.

The potential upside of asking is tremendous, says Wong. If they say "yes," then "your life just changed! It's amazing how much asking can bring to you. ... It's phenomenal."

The always-be-learning philosophy, says Wong, is not reserved for just business. He notes that a hallmark of creative people is that they apply lessons from one discipline to another area of their lives.

Learn how to dance or how to cook, he suggests. "Anything that constantly increases your mind and how it can think." He recently learned how to scuba dive, for example.

Take "experiences from different areas and ... connect them to come up with new concepts," says Wong.
